Looks like whatever changes they made to trash killed Incinerators. I have 3 that were going full power prior to the patch and not there's no trash for them to process. They don't even send trucks now.
I had two incinerators that were not producing power. I added a few transformers and set one of my landfills to empty and that seems to have fixed the problem.
I see my trash reduction decreasing steadily over time. Although I've had my map on 3 speed for 20 minutes and my CIMs are still pissed about trash pickup. Hoping it improves over the next hour. My processing speed is in the green and my landfill capacity is now at 50%.
